Plugable USB 2.0 UGA stop working?

Was working fine now the green/yellow display light does not come on. I have used the USB 2.0 for the last several months without incident, but now it seems to have gone dead.

Hi Jonathan,

Thanks for posting here! I’m sorry to know about the trouble you are having with the Plugable UGA-2K-A. The green LED on the adapter does not light up when:

  1. The unit does not receive enough power because it is plugged into a port that does not provide the required 500mA of power or because of a failing USB Cable

  2. Display to that monitor is disabled

  3. The driver is not installed or is corrupted

  4. The unit itself has failed.

Could you connect the adapter to the system and run the DisplayLink Support tool (instructions here:… ) and email the resulting .zip to along with your Amazon Order ID and a link to this thread?

It would give us a better insight as to what is going on and how to resolve it.
